Sir Chris Hoy has kick-started Glasgow's one-year countdown to the Commonwealth Games, the largest multi-sport event ever hosted in Scotland.
The opening ceremony will take place at Celtic Park on July 23 next year, when athletes from across the Commonwealth will officially begin their 11-day quest for medals.
It is only the third time Scotland has staged the event since it began in 1930, and the first time Glasgow has played host.
Thousands of athletes, sporting and civic officials and spectators will descend on the city as 71 nations compete in 17 sports from badminton to boxing.
An army of 15,000 volunteers have been recruited to make sure the 20th Games run as smoothly as possible.
With 365 days to go, almost all the sporting venues are already completed and open to the public, and city officials say they are pleased with the pace of progress.
Cycling legend Sir Chris, Britain's most successful Olympic gold medallist, was joined by Glasgow 2014 mascot Clyde on Buchanan Street today where Games organisers unveiled the official ticketing guide.
Sir Chris said: ``It's a real thrill to be in the heart of Glasgow today celebrating the One Year to Go milestone to the Commonwealth Games.
``Glasgow 2014 is the biggest sporting celebration coming to the UK next year, the biggest sporting occasion ever seen in Scotland and the next opportunity to see a wealth of top athletes and the next generation of superstars in action.
``The Commonwealth Games has a very special place in my heart. It's an occasion like no other in sport and I have no doubt that Glasgow and Scotland will ensure next year's Games are an unforgettable and enjoyable experience for athletes and spectators alike.
``I'd encourage everyone to be part of this. Roll on next year and bring on Glasgow 2014.''
Sir Chris announced his retirement earlier this year and will not compete at the Games and the new velodrome named in his honour.
